Giants third baseman Pablo Sandoval has been experiencing discomfort in his right elbow for over two weeks and felt renewed pain Friday after making a pair of plate appearances in a Cactus League game. But he still hasn’t been ruled out for Opening Day.

“It’s going to go down to the wire,” manager Bruce Bochy told Alex Pavlovic of the San Jose Mercury Newson Saturday. “It won’t be an easy call, but we’re pretty optimistic that he’s going to make it.”

“I’m feeling better,” added Sandoval when asked about the elbow. “If I’m allowed to, I’m going to be there.” If the Giants decide to play it safe, Joaquin Arias will probably get the fill-in start at the hot corner.

Sandoval, 26, batted .283/.342/.447 with 12 home runs and 63 RBI over 108 games last summer for the eventual World Series champions. He appeared in 117 games with the Giants in 2011.
